Blythe Kelvinmas!

"A boy should have learnt by the age of twelve to write his own language with accuracy and some degree of elegance; he should have a reading knowledge of French, should be able to translate Latin and easy Greek authors and should have some acquaintance with German."

In addition to these minimum accomplishments, by the age of twelve Kelvin had won a prize for translating a dialogue of the Greek satirist Lucian and was in His second year at the University of Glasgow. What had you accomplished by the age of twelve?
